How do you remove chips from a drilled resin hole?

Drilling holes in a resin sink or other resin project can sometimes leave behind small chips or rough edges. Achieving a clean, tidy result requires just a few careful finishing steps. Here’s how you can successfully remove chips from a drilled resin hole.

Smoothing the Edges

Once you’ve drilled the hole, inspect the edge for chipped or uneven areas. The best way to smooth these imperfections is to gently sand the edge using fine-grit sandpaper, ideally starting with 400 grit and progressing to a finer grade if needed. Work lightly and evenly around the hole, taking care not to widen it. Alternatively, a deburring tool is specifically designed to clean up drilled holes and can offer precise results when dealing with resin surfaces.

Finishing Touches and Clean-up

After sanding, use a soft brush or clean, dry cloth to remove any dust. You may also want to wipe the area with a damp, lint-free cloth to pick up all remaining particles. For additional shine or a perfectly smooth finish on decorative resin items, a quick hand polish can be used after sanding. If you are working on a resin art piece—for example, one made with the techniques in our Kiwi Coasters video lesson—a neat finish is essential for professional-looking results.

When This Matters Most

When installing taps or drains in a resin sink, as leaks or fitting issues can occur if chip debris is left unchecked.
In decorative resin art or functional trays, where smooth edges enhance safety and visual appeal.
